Description

  The present invention relates to a bag.

  For example, a shoulder bag has a surface close to the user's back. For this reason, there are problems such as the occurrence of stuffiness and the surface becoming wet with sweat.

  In order to solve this problem, Patent Document 1 discloses a bag in which a contact portion with a body is constituted by a three-dimensional net.

JP 2004-148006 A

  However, although the three-dimensional structure net has a high porosity of, for example, 90% or more, it is difficult to secure a space between the body and the fabric at the portion in contact with the body, and therefore the flow of air for moving and releasing moisture It is difficult to ensure. As a result, it is the actual situation that the effect that I imagined is not obtained.

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to solve such problems and to surely release the moisture at the contact portion of the bag with the body to the outside.

  In order to achieve the above object, the bag of the present invention has an uneven portion formed of a double raschel knitted fabric formed on at least a part of the surface of the portion in contact with the user's body. The Russell knitted fabric is formed by forming narrow knitted fabrics at intervals, and the narrow knitted fabric has a plurality of thick portions and narrow portions alternately along the longitudinal direction thereof. .

  According to the bag of the present invention, the narrow knitted fabric is preferably semicircular in cross section.

  In addition, according to the bag of the present invention, it is preferable that the bag is of a backpack type and that the uneven portion is arranged in the direction of the height of the user carrying the back when the bag is carried.

  In addition, according to the bag of the present invention, it is preferable that the bag is of the backpack type and that the uneven portion is arranged in a direction intersecting with the height direction of the user carrying the back when the bag is carried on the back.

  Moreover, according to the bag of this invention, while being a backpack type | formula, it is suitable that the uneven part is formed in the shoulder strap.

  According to the bag of the present invention, at least part of the surface of the portion in contact with the user's body is formed with an uneven portion formed of a double raschel knitted fabric, and the double raschel knitted fabric of the uneven portion is The narrow knitted fabric is formed at intervals, and the narrow knitted fabric has a plurality of alternately a wide width portion and a narrow width portion along its longitudinal direction. A space in the longitudinal direction of the narrow knitted fabric is formed between the body and the surface of the fabric in the concave portion of the concave and convex portions, so that air containing moisture can move smoothly. For this reason, a user's feeling of stuffiness can be improved significantly. In addition, since the contact area with the body is small compared to the case where the concavo-convex part makes full contact even in a sweaty state, skin separation is good and the discomfort of the body can be greatly reduced.

  Furthermore, since the narrow knitted fabric as the convex portion of the concavo-convex portion has a plurality of thick portions and narrow portions alternately along the longitudinal direction, compared with the case where the narrow knitted fabric has a constant width, Since the shape becomes complicated and it is difficult to fall down, and the recess is only partially narrowed along the length direction, so that the passage of air can be ensured. The effect of being less likely to collapse is further ensured by the semicircular cross section of the narrow knitted fabric.

  According to the bag of the present invention, it is a backpack type, and when the concave and convex portions are arranged in the direction of the height of the user who carried the back, air containing moisture is provided in the concave and convex portions. In addition to being able to move more favorably, when the bag is about to be displaced laterally with respect to the body, the concavo-convex portion becomes a resistance, and the occurrence of such displacement can be effectively prevented.

  According to the bag of the present invention, the bag has a backpack type, and when the bag is carried on the back and forth, the uneven portion is arranged in a direction crossing the height direction of the user carrying the back, so that the bag weights the body. Therefore, the uneven portion becomes a resistance when trying to shift up and down, and the occurrence of such a shift can be effectively prevented.

  According to the bag of the present invention, the shoulder strap is not only capable of producing the same effects as described above, but also having a concave and convex portion formed on the shoulder strap. When the weight on the bag side is received by the shoulder by the action of the above, the blood flow in the shoulder can be ensured by the bumpy portion hitting the shoulder.

It is a three-dimensional view of the bag of embodiment of this invention. It is a typical top view of the principal part of the uneven | corrugated | grooved part in the bag of FIG. It is typical sectional drawing of the principal part of the uneven | corrugated | grooved part in the bag of FIG. It is a three-dimensional view of the bag of other embodiment of this invention. It is a three-dimensional view of the bag of further another embodiment of this invention. It is a figure which shows the use condition of the bag of FIG.

  FIG. 1 shows a shoulder bag according to an embodiment of the present invention. The bag includes a bag body 11 and a pair of shoulder straps 12. Concave and convex portions 13 are respectively formed on the back support portion of the bag body 11 and the surface portion of the shoulder strap 12 on the body side of the user.

  The concavo-convex portion 13 is configured by a specific double raschel knitted fabric. As shown in detail in FIGS. 2 and 3, the specific double raschel knitted fabric constituting the uneven portion 13 has a special structure different from a general double raschel knitted fabric. Specifically, the double raschel knitted fabric constituting the concavo-convex portion 13 includes a surface fabric having a configuration in which a plurality of narrow knitted fabrics 14 having a semicircular cross section are disposed at intervals as convex portions in the concavo-convex portion 13. The lining 15 made of a flat knitted fabric is integrated with the connecting yarn 16. The narrow knitted fabrics 14 are formed spaced apart from each other in the direction of the height of the user who carries the bag as shown in the figure, or are formed spaced apart from each other in any other direction. Accordingly, a groove 17 as a concave portion in the concave and convex portion 13 is formed between the adjacent narrow knitted fabrics 14.

  As shown in FIG. 2, the narrow knitted fabric 14 is formed by alternately arranging the wide width portions 18 and the narrow width portions 19 along the longitudinal direction thereof, that is, in the direction of the height of the user who carries the bag in the example of FIG. Have multiple. The reason will be explained. As shown in FIG. 3, the concavo-convex portion 13 has narrow knitted fabrics 14 and grooves 17 formed alternately. If the narrow knitted fabric 14 is formed narrow and the groove 17 is formed wide when forming the concavo-convex portion 13, when the load, for example, the weight from the bag body 11, is applied to the narrow knitted fabric 14, It falls and closes the groove 17. Then, the air flowing through the space formed by the groove 17 prevents the moisture from the user's body from escaping to the outside. On the contrary, if the narrow knitted fabric 14 is formed widely and the groove 17 is formed narrowly, the passage of air and moisture in the groove 17 becomes worse. On the other hand, as described above, the narrow knitted fabric 14 has the wide width portions 18 and the narrow width portions 19 alternately, so that the shape of the narrow knitted fabric 14 is complicated compared to the case where the width is constant. In addition, it is difficult to fall down, and the groove portion 17 is only partially narrowed along the length direction, so that air and moisture can be secured. Since the cross-section of the narrow knitted fabric 14 is semicircular, the effect of preventing the knitted fabric 14 from falling down is further ensured.

  The outer material and the lining material in the uneven portion 13 are knitted using a general multifilament yarn. Typical examples of general multifilament yarns include polyester multifilament yarns and false twisted yarns thereof. The multifilament yarn is suitably selected within the range of 55 dtex / 24 filament to 400 dtex / 150 filament. A rigid monofilament yarn is used for the connecting yarn 16. The reason why the rigid one is used is to secure the groove 17 in a state where the narrow knitted fabric 14 is erected. As the monofilament yarn, a polyester monofilament yarn is preferable, and one having a fineness of about 20 to 100 dtex is particularly preferable.

  The double raschel knitted fabric constituting the uneven portion 13 is knitted using a known double raschel knitting machine. However, the use of the yarn is different, and the yarn to be supplied for the outer material knitting is pulled out at an appropriate interval, and the connecting yarn for connecting the outer material to be knitted with this yarn is pulled out. The grooves 17 are knitted. That is, knitting is performed by providing guides for not supplying yarns (guides for yarn removal) at appropriate intervals in the guide rows for supplying the yarns for knitting the outer material and the connecting yarns 16. As a result, the groove 17 is formed without knitting the outer material that should originally be knitted in the wale direction. On the other hand, the knitted outer fabric has both side edges in the wale direction wound around the lining 15 and becomes a narrow knitted fabric 14 having a semicircular cross section. The reason why both side edges in the wale direction are wound on the lining 15 side is that the both side edges are pulled to the lining 15 side by the connecting thread 16. The lining 15 becomes a flat knitted fabric by knitting in the same manner as usual without threading.

  A detailed knitting method is that when the outer material is knitted, the yarn for knitting the outer material and the connecting yarn 16 are removed only by 1 to 3 wales with respect to 5 to 15 wales, so that the cross section is semicircular. Thus, a double raschel knitted fabric in which the outer fabric in which the narrow knitted fabrics 14 are arranged at intervals and the lining 15 formed of a flat knitted fabric are integrated by the connecting yarn 16 can be obtained. Further, if a stretched false twisted yarn is used as a yarn for knitting the lining 15 and is pulled and fixed in the course direction after knitting, the width of the groove 17 formed between the narrow knitted fabrics 14 is increased. Can do. In the double raschel knitted fabric obtained by such a knitting method, the width of the narrow knitted fabric 14 is about 2 to 8 mm, and the width of the groove 17 is about 3 to 10 mm. The depth of the groove 17 is about 1 to 5 mm. As the knitting structure of the narrow knitted fabric 14, a cord structure or a denby structure can be adopted. As the knitting structure of the flat knitted fabric that becomes the lining 15, a chain knitting structure in which chain knitting yarn rows are connected by an insertion yarn can be employed.

  The wide width portion 18 and the narrow width portion 19 can be formed by increasing or decreasing the yarn supply amount during knitting. When the supply amount of the yarn is increased, the wide width portion 18 is formed, and when the supply amount is decreased, the narrow width portion 19 is formed. By repeating this, the wide portions 18 and the narrow portions 19 are alternately formed. The supply amount of the yarn can be adjusted, for example, by changing the supply amount of the connecting yarn 16 by an electro beam control method manufactured by KARL MAYER. Alternatively, it can also be performed by an MSS control system in which the winding and feeding beam are controlled while keeping the yarn tension constant.

  According to the shoulder bag shown in FIG. 1, when the user carries this bag and the uneven portion 13 comes into contact with the body, the narrow knitted fabric 14 is provided between the body and the fabric surface in the groove 17 of the uneven portion 13. A longitudinal space is formed. In the illustrated example, this space is formed in the height direction of the user, that is, in the vertical direction. For this reason, since the air containing moisture can move smoothly, a user's feeling of stuffiness can be improved significantly. Even in a sweaty state, the concavo-convex portion 13 has a smaller contact area with the body as compared with the case where the entire surface is in contact with each other, so that the skin separation is good and the discomfort of the body can be greatly reduced. In the bag of FIG. 1, the concavo-convex portion 13 is formed on almost the entire surface of the back support portion. However, the concavo-convex portion 13 does not necessarily have to be formed on the entire surface of the back support portion, and only the main portion thereof. It can also be formed.

  In the bag shown in FIG. 1, since the uneven part 13 is formed also in the shoulder strap 12, the same effect as the backrest part can be acquired also in this shoulder strap 12. FIG. In addition, when the weight on the bag side is received by the shoulder of the user, the blood flow in the shoulder can be ensured by the uneven portion 13 hitting the shoulder. The effect of ensuring the blood flow is remarkable in the shoulder strap 12, but can also be exerted in the same manner by the uneven portion 13 of the backrest portion.

  The concavo-convex portion 13 can easily move the air containing moisture as described above in the longitudinal direction of the narrow knitted fabric 14 and can exhibit good slipperiness with respect to the body. In addition, in the direction intersecting with the longitudinal direction of the narrow knitted fabric 14, particularly in the direction orthogonal to the longitudinal direction of the narrow knitted fabric 14, an anti-slip effect on the body can be exhibited. For this reason, by making the longitudinal direction of the narrow knitted fabric 14 an appropriate direction, it is possible to exert an effect of preventing the displacement with respect to the human body in a direction intersecting the long knitted fabric 14, particularly in a direction orthogonal thereto. For example, in a bag used when exercising with intense vertical movement such as trail running, as shown in another embodiment of the present invention in FIG. Can be reduced.

  FIG. 5 shows an example in which the uneven portion 13 is formed on a one-shoulder type bag according to still another embodiment of the present invention. In the illustrated example, the uneven portion 13 of the backrest portion is formed at an appropriate angle with respect to the vertical direction of the bag, for example, in a direction inclined at 30 degrees.

  FIG. 6 is a view of a state in which the bag of FIG. 5 is carried by the user as seen through the user's body from the chest side of the user. The shoulder strap 12 is hung from the right shoulder of the user toward the left flank on the chest side of the user. As shown in FIG. 5, the concavo-convex portion 13 formed at an appropriate angle with respect to the up-down direction of the bag is oriented in the direction of the user's height in the state of being shouldered as shown in FIG. Each function of can be demonstrated.

  Examples of the bag according to the present invention include bags other than the backpack type. Even if it is such a bag, the uneven | corrugated | grooved part 13 can be formed similarly and the same effect can be exhibited.
